Apologies for the constant questions. Really enjoying the course and I have learnt loads!
My question is about the services quiz. I understand how the logic works and I have implemented the solution for the most part. My confusion is surrounding the side variable. How are we meant to use this to extend the length of the square. Are we meant to be using a time delay, so the larger the time delay, the longer the time between publishing movement and publishing stopping movement for each side of the square. Or are we meant to be using a sensor I am not aware of to measure distance.
